Not sure if this is really relevant to this post, but thought maybe some folks might find this experience erotic.....
One time I was involved in a threesome with two other guys. We stripped down, and were standing naked together -- hugging, kissing, rubbing, and feeling each other's growing erections. I decided to crouch down and start sucking one of the guys, who quickly became very hard. He continued kissing the other other guy while I was sucking his shaft and licking his hairless balls. Soon, he indicated that he was getting close to cumming, and wanted me to stop, so he could extend his pleasure before reaching an ultimate climax.
For some reason, I just couldn't stop myself from sucking his rock hard penis. I wanted to feel his penis pulsating inside my mouth as he orgasmed, and feel his cum filling my mouth. He quickly reached that point of no return, and groaned loudly in ecstasy as his penis throbbed inside my mouth. He filled my mouth with his white gold!
I stood up, and gave the other guy a passionate kiss, and pushed some of the cum from inside my mouth into his mouth. He subsequently kissed the guy who had just orgasmed, and gave him a taste of his own cum. We had cum full circle!
